HEATlNG-DRUNI.

ESPECIPIC'ATION forming part of Letters Patent No. 387,750, dated August 14, 1888.

Application tiled March 2, 1888.

To all whom it may concern.-

Be it known that I, J EREMIAH J. SULLIVAN, a citizen of the United States, residing at Oswego, in the county of Oswego and State of New York, have invented new and useful Improvements in Heating-Drums, of which the following is a specification.

My invention relates to improvements in heatingdrums; and it consists in a certain novel construction and arrangement ofdcvices which are fully set forth hereinafter, and illustrated in the accompanying drawings, where Figure 1 is a side View of the improved heater. Fig. 2 is a vertical central section of the same. Fig. 3 is a similar view on the line a: an of-Fig. 2. Fig. 4 is a horizontal section on the line ;1 y, Fig. 2.

Referring by letter to the drawings, A designates the outer casing or drum, having the conical caps B B on its upper and lower ends, in which are inserted the ends of the stovepipes G C.

I) represents the hot-air chamber, which comprises the conical upper compartment, E, and the cylindrical lower compartment, F, the lower end of the upper compartment being larger than the lower compartment, thus forming a shoulder, G. The lower end of the drum is closed by the plate H, thus cutting the space within the conical cap off from the interior of the drum and forming a separate reeeiving-chainber, I. The lower stove-pipe, which isabove described as entering the lower conical cap, passes entirely through the said reccivingchainber and communicates with the interior of the drum.

K K represent small conducting-llues,wliicl1 pass from the receivingchamber (upon opposite sides of the lowersmokc-pipe) to the lower end of the lower compartment of the hot-air chamber, thus establishing communication be tween the said chambers. These flues,althongh passing through and located in the drum, do not communicate therewith.

L represents a cone-shaped dcilectonwhich depends from the lower end of the hot-air chamber around the upper ends of the conducting-fines, the said deflector being disposed directly over the upper end of the lower smokepipe. The mouth of the deflector is Serial No. 265,909. (No model.)

larger than the pipe, and its lower edge comes within a short distance of the plate H at the lower end of the drum.

M M represent hot-air-disehargc fines which communicate with the upper end of the upper compartment of the hot-air chamber, and they diverge toward their upper ends and pass through openings in the sides of the conical cap at the upper end ofthe drum.

Openings N N are formedin the sides of the lower conical cap, B, thus establishing communication between the receiving-chamber and the outside air. It will now be readily seen that a passage is formed directly through the heater from the receiving-chamber to the discharge-pipes; but the said passage is entirely isolated from the interior ofthe drum and the smoke-pipes which communicate therewith.

A deflecting-disk, O, is arranged in the upper compartment of the hot-air chamber close to the shoulder G, and its edges come close to the sides of the said upper compartment, therefore overlapping the shoulder. The disk is held in place by small spring clips or supports P P,which are attached to the said shoulder G, and are provided with small notches to engage the edges of the disk.

It will be evident that the annular opening 0 between the edge of the disk and the side of the hot-air chamber may be increased or diminished in size by altering its position vertically in the compartment The operation of the heater is as follows: The smoke, gases, and other products of con1- hustion pass up the lower smoke-flue and are projected into the conical deflector arranged above the upper end thereof, and this causes the said products to rebound and pass downward under the edge of the deflector. The smoke, gases, 8cm, then pass up through the body of the drum (around the hotair chamher and the fines communicating therewith) and escape through the upper smokepipe. The progress of the products through the drum is impeded as much as possible without interfering materially with the draft, so as to deprive them of their heat. The deflector above the upper end of the lower smokepipe concentrates the heat upon the lower end of the hot-air chamber and the upper ends of the conducting-ii ucs,which absorb a large proportion of the heat. As the smoke passes up through the drum, the sides of the latter, as well as the sides of the hot-air chamber, absorb still more, and the shoulder at the upper end of the lower compartment of the hot-air chamber, (causing the smoke and gases to pass through a small annular opening,) and the upper conical cap, B, serve to confine the smoke, &c., until the remaining heat is extracted.

From the above it will be seen that much heatwill be radiated from the sides of the body of the drum, and the heat which is absorbed by the sides of the hot-air chamber is radiated into the interior of thelatter,thereby heating the air contained therein and causing it to rise. The said heated air passes from the hotair chamber through the dischargeflues into the room, thereby causing the outside colder air to rush into the receiving-chamber through the openings in the sides thereof, andascend through the conducting-fines into the hot-air chamber. It will be readily seen that as the air passes through the various parts of the passage through the drum, above described, it will become heated and pass out through the dischargeflues, thus causing a continuous current of air into the receivingchamber and out of the discharge-fines.

The above-described disk in the hot-air chamber is designed to obstruct the passage of the air somewhat, so as to enable it to become thoroughly heated before passing out of the drum, and it is further designed to cause the air to pass close to the sides of the chamber from which the heat proceeds.

Having thus described my invention, I claim- 1. The combination of the drum having the pipes (J G communicating with its upper and lower ends, the receiving-chamber located at the bottom of the drum around the lower pipe, 0, the hot-air chamber located in the drum and communicating with the receivingchamber through suitable pipes, K, and provided at an intermediate point with a shoulder or offset, forming an. annular passage be tween its edges and the sides of the drum, and the outlet-fines M at the upper end of the hot-air chamber, substantially as and for the purpose specified.

2. The combination of the drum, the smoke pipes, and the hot-air chamber located in the drum and comprising the upper conical compartment, E, communicating with the outside air through suitable outlet tubes, and the lower compartment, F, communicating with the outside air through suitable inlet-tubes, and communicating with the upper compartment, E, through an annular opening, 0, substantially as and for the purpose specified.
